Tag: A turntable rotates counterclockwise at 78 rpm. A speck of dust on the turntable is at 0.44 rad at t=0

A turntable rotates counterclockwise at 78 rpm. A speck of dust on the turntable is at 0.44 rad at t=0 ,What is the angle of the speck at t = 7.9 s? Your answer should be between 0 and 2π rad. Convert rpm in radians ω = 78rpm = 78*2π/60s = 8.164 rad/s angular displacement when t = 7.9s θ = 8.164 rad/s * 7.9  = 64.49…
